It seemed to happen in slow motion. The green jet flew towards him as he turned, and he was too late, too late, and Ginny cried, "No!" as the jet came closer still… And then Ginny was falling, falling before him, crumpling to the ground… and she was gone.
Dead.
Never to return, never to smile, or laugh, or kiss again…
A heartrending cry tore the air – his? – as he fell to his knees… it couldn't be… not Ginny…
Amidst the crowd of Death Eaters, someone laughed.
Suddenly he was up again, in a movement so fast that even he did not notice it. He would pay. They would all pay.
Hexes and jinxes and curses flew through the air, felling the Death Eaters, and they crumpled and fell and froze… None could withstand him, none could fight him; he destroyed them, all of them, until he reached the one who had sent the Killing Curse. And he Cruciated him until he writhed and screamed and begged for mercy, and still kept on, and the pain and the fury in his face was terrible to behold.
